Abstract
The disclosure relates to a Josephson junction formed by a non-superconducting barrier between two superconducting films of the (R) BaCuO (R=rare earth) group. In order to take advantage of the greater coherence length of superconductors along the CuO planes, i.e. perpendicularly to the long axis 'c' of the crystal unit cell, the superconducting film is oriented so that the axis 'c' is parallel to the plane of the junction. The device can be applied to Josephson junctions and to SQUIDs.
